Understanding Your Flow Meter’s Capabilities

There are pros and cons in choosing any flow meter but to us at Icenta, there are very clear advantages to the new age range of thermal mass flow meters over the traditional Variable Area (VA) meter, often referred to as Rotameters. In this post, we try to help you in understanding your flow meter’s capabilities by discussing the limitations of VA, the types of thermal mass flow meters, the principle of...

Variable Area Flow Meters available for Basic Flow Applications

icenta’s flow meter portfolio now includes a range of cost effective, mechanical flow meters that require no auxiliary power and provide direct viewing of flow rate. Variable area flow meters operate on the principle that the variation in area of flow stream required to produce a constant pressure differential is proportional to the flow rate. The flowing fluid enters the bottom of the meter, passes upward through...
